This application is a division of our co-pending application Ser. No. 117,597, led September 24, 1949, now Patent No. 2,584,760, Feb. 5, 1952,

This invention relates to improved apparatus for the waving of human hair and more particularly to apparatus which is intended to impart what is known as a permanent wave to the hair.

In order that the principle of the invention may be readily understood, we have disclosed several embodiments thereof in the accompanying drawing wherein:

Fig. 1 is a longitudinal elevation of one embodiment of the invention wherein the main or body member is of the so-called clothespin form, and wherein a clamping or cam member is provided that is pivoted at one end to the main or body member;

Fig. 2 is a vertical transverse section on the line Z--Z of Fig. l; and

Fig. 3 is a view similar to Fig. l, but of an embodiment of the invention wherein the main or body member is solid, with a roughened surface.

Both of the embodiments of the invention herein disclosed have a number of advantages over the conventional types of hair curlers. In the invention herein disclosed, as represented in Figs. 1 and 2, no paper is needed for holding the ends of the hair in position when winding begins. Also, the curler can be withdrawn from the hair without unfurling the curl thereof, in the form represented by Figs. l and 2, Whereas most other types of curlers with which we are familiar, including that represented by Fig. 3, require unwinding oi' the curl in order to remove the curling bar. Moreover, the parts of the curler oi our invention are in their functioning position held rmly locked together, thus allowing the curler to be positioned tight to the head or scalp without any slack occurring.

In that embodiment of the invention shown in Figs. 1 and 2, the main or body member is represented at 23, and it is desirably of the biiurcated or clothespin form shown in our application Ser. No. 117,597, now Patent 2,584,760, Feb. 5, 1952, Figs. 1 and 2 thereof, thus providing two flexible portions 2li, 25 that receive the hair between them and which may be gently pinched together in the same manner as in the use of the structure shown in Figs. 1 and 2 of said application 117,597, now Patent 2,584,760, Feb. 5, 1952, the said main or body member 23 is provided with a solid head 26 which may be knurled as indicated or provided with ats or the like to facilitate gripping, and adjacent thereto it is provided with two annular ribs 27, 28 between which is received a yoke or piece 29, 2, that encircles the main or body member 23 in such manner as to be freely turned thereon excepting when the part carried by the yoke (now t0 be described) is in locking position. The two ends 3D, 3l of the yoke E9 extend suciently to receive between them the cooperating member 32 which has a free end 3.3, said member 32 being of elongated form as shown in Fig. 1 and, more specifically stated, it is of a bow shape or elongated attened-arc shape. The said co-operating member near its inner end has a transverse opening through which passes a pivotal pin Sli, the ends of which `are xedly received in the ends 99, 3i of the yoke 29. The said co-operating member 32 has a cam end or portion 35 extending inwardly sufficiently so that when said `izo-operating member 32 is turned downward into the position shown in Fig. l, said cam end or portion frictionally engages the surface of the main or body member 23 between the ribs 27, 28, and thereby locks or frictionally holds said cooperating member 32 in its functioning position. in order most eiectively to clamp or lock the said co-operating member 32 in its functioning position, the pivot 3l! of the co-operating member 32 should be so located and the cam end or portion 35 should be so formed that the said cam end or portion 35, when in its clamping position, engages the surface of the main or body member 23 at a point between the outer end of the head 26 and a plane normal to the longitudinal axis of the said main or body member 23 and passing through the said pivot .74% oi the said cooperating member 32. The cam end or portion 35, as shown in Fig. 2, is concaved at its extreme inner end to engage the rounded surface of the main or body member 23 throughout an eX- tended arc.

When the co-operating member 32 is turned upward into vertical or upright position, the inner end of said cam member 35 rises above or becomes separated from the surface of the main or body member so as to be freely rotatable relative to said `co-operating member 32.

The embodiment of the invention shown in Fig. 3 is similar in all respects to that shown in Figs. 1 and 2, excepting that the main or body member indicated at 23a is of solid form with longitudinally extending ridges 35. The same numerals are therefore used as in Figs. l and 2. With this type of curler it is customary to use paper to pick up the loose ends of hair and to grip the hair when starting the curl.

While the parts of the two embodiments of the invention may be formed of any suitable material, they are desirably formed 0f some suitable flexible material such as plastic. Also desirably, in each embodiment of the invention herein disclosed, the two parts of the device are made in contrasting colors, such as red, and white, or any other contrasting colors.

It will be noted that in the embodiments of the invention shown the co-operatingy member is of boweshape or elongated-arc shape, to engage the main or body member only at' or adjacent to the nd portions thereof. In all forms of the invention, the two members are locked or held together with the hair curled `between them.

Having thus described two embodiments of the invention, it is to be understood that although specific terms are employed, they are used in a generic and descriptive sense, and not for purposes `of limitation, the scope of lthe invention being set forth in the following claims.

We claim:

1.. Ahair-waving curler consisting of a main or body member having a head at one end and a clamping member mounted upon said main or body member adjacent said head, said clamping member for so. mounting it upon said main or body member having movably mounted at one end a separate piece that at least partly enciroles and is itself turnable freely about the main or body member adjacent said head, said clamping member being movably mounted upon said turnable separate piece, so as to be swung into either clamping or open position, the said clamping member having substantially at its end a cam formation that, when said clamping member is swung downward into closed, functioning position, engages the surface of the main or body member so as to preventk rotation of said clamping member about the main or body member, and that, when the clamping member is swung into open position, isY free from camming engagement with said main or body member.

2. A hair-waving curler consisting of a main or body member having a head at one end and a clamping member mounted upon said main or body member adjacent said head, said clamping member for so mounting it upon said main or body member having pivoted at one end a yoke that substantially encircles and is itself turnable freely about the main or body member adjacent 4 said head, the said clamping member being transversely pivoted upon the adjacent ends of said yoke, so as to be swung into either clamping or open position, the said clamping member terminating at its inner end in a cam formation that, when said clamping member is swung downward into closed, functioning position engages the surface of the mai-nior body member so as to prevent rotation of ysaid" clampingk vmember about the main or body member and that, when the clamping member is swung into open position, is free from camming engagement with said main or body member.
